Abstract:
The present invention provides for microfluidic devices and methods for their use. The invention further provides for apparatus and systems for using the microfluidic devices, analyze reactions carried out in the microfluidic devices, and systems to generate, store, organize, and analyze data generated from using the microfluidic devices. The invention further provides methods of using and making microfluidic systems and devices which, in some embodiments, are useful for crystal formation. In one embodiment, an apparatus includes a platen having a platen face with one or more fluid ports therein. The fluid ports spatially correspond to one or more wells on a surface of the microfluidic device. A platform for holding the microfluidic device relative to the platen is included, and a platen actuator for urging the platen against the microfluidic device so that at least one of the fluid ports of the platen is urged against one of the wells to form a pressure chamber comprising the well and the port, so that when pressurized fluid is introduced or removed into or from the pressure chamber through one of the ports, fluid pressure is changed therein.

The present invention provides microfabricated fluidic systems and methods. Microfabricated fluidic devices of the present invention include switches (232, 233) that can be opened and closed to allow or block the flow of fluid through a channel in response to the pressure level in a gate of the switch. The microfabricated fluidic switches may be coupled together to perform logic functions and Boolean algebra, such as inverters, AND gates, NAND, gates, NOR gates, and OR gates. The logic gates may be coupled together to form flip-flops that latch signals. The present invention also includes microfabricated fluidic pressure multipliers that increase the pressure (P2) in a second chamber relative to a first chamber. Microfabricated fluidic devices of the present invention also include pressure sources (560). A pressure source of the present includes a pump coupled to a reservoir through unidirectional valves (500). The pressure source may be high pressure source or a low pressure source. Microfabricated fluidic devices of the present invention may also include devices that perform analog functions such as switching regulator.
